Serial No. 330,775.

State of Ohio, have invented a certain new and useful Improvement inLinotypeMa-king Mechanism, of which the following is a full, clear, andexact description.

This invention is especially adapted. for use as part of a linotypemachine for the purpose of casting the linotype from an assembled lineof matrices, for trimming the sides of said linotype, and fordeliveringthe finished linotype into a galley or some other suitable receptacle.The invention may be summarized as the construction and combination ofparts hereinafter described and pointed out definitely in the claims.

In the drawing Figure 1 is a front elevation of mechanism embodying theinvention, when the trimming knives and their support have been removed,and when a part of the mechanism for transferring the finished'linotypeto the galley has been broken away. Fig. 2 is a front elevationof saidtrimming knives and their frame, and fragments of the transferringmechanism. Fig. 3 is a transverse vertical section in the planeindicated by line 33 on Fig. 4:. Fig. 4 is a plan view of the invention.Fig. 5 is a front elevation, partly broken away, of the trimming knivesframe, the trimming knives andthe p rts immediately associatedtherewith. Fig. 6 is a sectional plan in the horizontal plane of themold slot, at the right end of the knife frame; this figure being forthe purpose of showing the trimming knife I and the wipers near it. Fig.7 is a transverse sectional elevation in the plane inclicated by line 66on Fig. 4:. Fig. 8 is a transverse sectional view of certain parts ofthe mechanism, in the plane indicated by line 88 on Fig. 4.

Referring to the parts by reference letters,,A represents the mold blockwhich is removably secured in a recess in the slide B. This slide ismounted between horizontal guide rails c c of the frame member C, sothat it may move backward and forward in the horizontal path from aposition in which the mold is alined with the trimming knives D-D, and aposition in which said mold is alined with a pot nozzle L.

The trimming knives are adjustably mounted in a frame E which isremovably secured to the front face of frame C. The mold black A has theusual mold slot a; and this block is removably held in the recess, towhich it is fitted, in slide B, by means of spring-actuated taper endedpins G G. These pins are mounted in the ends of the slide, in positionsubstantially as shown, whereby they may engage in tapered holes inopposite ends of themold block. Suitablemeans may be provided forwithdrawing both pins so as to permit the removal of the mold block. Themechanism shown for this purpose consists of a rocker g pivoted at oneend to the head g of pin G, and at its other end to a longitudinallymovable rod which passes entirely through the slide and engages with thehead g of the other pin G. The pivots connecting this rocker with theparts mentioned must fit loosely either in the rocker or other partwhereby, when the rocker is rocked in one direction, it will firstwithdraw one of said pins GG,whichever is withdrawn most easily, andwill thereafter, by continuing its motion, withdraw the other pin.

The slide B may be moved backwardly or forwardly in the path mentionedby any suitable mechanism. As shown a lever H is connected by link itwith the slide. This lever is on the rock-shaft h to which also isattached an arm 71 having a friction roller if in its end. This frictionroller-is engaged by cam 70 attached to the rotatable shaft K, andthereby the rock-shaft h is so rocked that the slide B is moved to-theleft, that is to say, to the position which brings the mold in properalinement with the trimming knives. A spring 71 engaging with the arm itserves to rock the rock-shaft h in that direction which will move slideB to the other end of its path, viz; into position between the potnozzle L and a line of 'matrices M. The mechanism for moving the matrixline and the pot nozzleagainst opposite faces of the mold may be of anysuitable construction as, for example, like that shown in my priorpatent No. 791,747. The spring-actuated movement of the slide is limitedand rendered definite by the engagement of the end of the slide with apart 0 of the guide frame.

The frame O in which the mold slide B moves may be provided withpassages c 0 which extend horizontally in the overhanging rear parts ofthe frame members a e, and are connected through a vertical passage 0*in a vertical part c of said frame. By means of suitable pipeconnections with the left ends of the two passages 0 0 cold water, forthe purpose of keeping the mold and mold slide cool, may be circulatedthrough these water-ways.

The trimming knives D-D are, as before stated, supported in a frame E.This frame has upon its lower member two inclines e and e for engagementwith corresponding inclines (Z and d carried by the lower knife block.The upper member of this frame has the inclines e and c for engagementwith inclines (Z 6Z5 carried by the upper knife block. The angle of theinclines associated with the upper knife is greater than that of theinclines associated with the lower knife. The inclines carried by theknife blocks may be the ends of adjustable screws cl which screw throughthe knife blocks. Then these knives are in the frame they are separatedas far as possible by the action of springs N seated in recesses (Z inthe proximate faces of the knife blocks. A set-screw (Z which screwsthrough the end of the frame E bears against the ends ofboth .knifeblocks so as to move them simultaneously and equally in the frame. Theresult will be that the parallelism of the knife edges will bepreserved, while the distance between them will be changed to adapt theknives for trimming slugs of different thicknesses. It will, of course,be understood that when the distance between the knife blades is changedthe mold block A will be taken from slide B and another mold, having itsslot a of a different width, substituted. The slots in the differentmold blocks are so placed that it is desirable to have the upper knifeblock move downward farther than the lower knife block moves up, whenthe distance be tween said knife blocks is reduced. It is for thisreason that the inclines e and e are made steeper than the inclines eand e.

A gage block X is adjustably secured to the outer end of the adjustingscrew, and on it are graduation marks to be read in connection withother marks on the knife frame. To adjust the gage block, a linotype ofthe desired thickness is placed between the knives, which are then movedagainst said linotype. The gage block is then moved to and secured inthe position when a definite mark thereon registers with a mark on theframe. The knives may be moved away from this position whenever desired,and then restored to this position by again turning the screw to bringthe graduation marks referred to into line. These knife blocks are heldin the frame by means of plates 6 secured to'the front face of saidframe and plates a secured to the rear face of said frame. All of theseplates, however, lap over and engage with the outer faces of therespective knife blades.

After a linotype has been formed in the mold, and said mold has beenmoved into range of the trimming knives, said linotype is to be pushedfrom the mold and between these trimming knives by an ejector P. Theknife frame E is secured to the front face of the frame C in which slideB moves. The ejector blade is removably clamped to a slide Q, which, ismainly supported on guide rails 0", but which preferably has a dependingarm 9 which is slidably mounted upon the shaft R by which it isadditionally guided. Preferably some mechanism for moving this ejectorslide will be provided, but any suitable mechanism may be employed.

When the finished linotype is ejected from the mold, and pushed throughthe trimming knives it is delivered to a transferring device T. Thisdevice has an arm having in it a longitudinal slot 2f whose front wallis beveled or rounded off as shown at t. The linotype is pushed entirelyacross this slot by the ejector blade, and left with its forward edgeresting upon the beveled top of said arm. hen the ejector is withdrawn,the rear edge of the linotype, being unsupported, will fall by gravitydown into said slot. This slot is inclined downward toward its outerend, at an inclination sufficient to cause the linotype to slide out ofit if permitted so to do. A spring-actuated retaining dog S is pivotedto the arm, and has a toe 8 extending in front of the open end of saidslot. Adjacent to the other end of this dog there is a slot 6' in thearm adapted to receive afixed tripping pin U. The arm T is secured to asleeve 22 which is rotatably mounted upon a vertically movable shaft V.This sleeve has in it a spiral groove t into which projects a fixed pinU. An arm to fastened to this shaft carries a friction roller 10 whichrests upon a cam t0" attached to the rotating shaft K, and the action ofthis cam is to lift the shaft and sleeve, whereby, through theinteraction of said pin U and spiral groove 2?, the sleeve is turned toa position where the linotype in slot 2 may slide out of the same into agalley or other receptacle. hen said sleeve 23 has been turned in themanner stated, the rear end of dog S will be brought into contact withpin U and, thereby, this dog wilL-be so swung as to release thelinotype, and permit it to slip out of the slot in said arm.

It is desirable, and perhaps necessary, that both faces of the moldblock and both trimming knives and pot nozzle shall be wiped after eachuse thereof. For this purpose four wiping devices are provided, two ofthem F and J are pivoted to the fixtures C, and are for the purpose ofwiping the oppoames site faces of the mold. The two other wipers O and Zare pivoted to the moldslide B and are for the purpose of wiping thetrimming lmives and nozz'le respectively. These wipers are alike in thateach includes a frame which is-pivoted on avertical axis to the movableslide B or to a fixed part of the device, and has a wiper arm, andcarries a friction producing device. When the wiper frame is pivotedtothe slide B, this friction producing device carried by the wiper frameengages with afixed part of the frame; and when the wiper is pivoted toa fixture, tnis friction producing device engages with the movable slideB. The movement of the slide, therefore, causes friction between thefriction producing device and the part with which they engage, with theresult of cansing the wiper frames to swing upon their pivots and movetheir wipers either against the part to be wiped or away from that part,as the case may be. The wiper frame F is pivoted to the top and bottommembers 0 c of the frame C. The top and bottom members of said framebeing connected by amember f which lies close to the rear face ofthemold, and has a wiper pad f" for engaging with said mold face bot-habove and below he mold slot and said frame carries spring-actuatedfriction pin f which passes through a relatively large hole in thetopframe member 0 and engages with the top of the slide B. The wiperframe J is pivoted to the knife frame E and has a wiper arm j forengagement with the front face of the mold. This frame also carries aspring-actuated friction pin y" which engages with the slide B. When theslide moves to the right, these wiper frames will be moved upon theirpivots by the friction so as to carry their wiper arms respectivelyagainst opposite faces of the mold. hen the slide is moved in the otherdirection these wiper frames are rocked in the other direction.

The wiper frame 0 is pivoted to slide B and has a wiper arm 0, forengagement with knife blades, and a spring-actuated friction pin 0 forengagement with the lower frame member 0. The movement of slide B to theleft causes the wiper frame to so swing that the wiper arm will engagewith and wipe the knife blades. \Vhen the slide moves in the otherdirection the wiper frame is so swung that the wiper arm is withdrawnfrom contact with the knife blades.

The wiper frame Z is pivoted to slide B, near the right end of the sameas shown in Figs. 4 and 6. It carries a wiper 2 for engagement with thefront face of the pot nozzle. It carries a friction pin 2 which engageswith one of the fixed frame members c 0. Then the slide B moves to theright, the friction between the pin 2 and the frame member causes theframe to swing upon its pivot so as to carry the wiper 2 against theface of the pot nozzle. 1". hen the slide B moves to the left this frameswings in the opposite direction.

A knife I is fixed in the frame member 0*, and it is placed in suchposition that it engages with the rear face of the moldin the line ofthe slot therein, and thereby trims the bottom of the linotype in saidmold slot, when the mold is being moved from the casting position to theejecting position.
